Step-by-step

  1. 1
    Contact customer service — in writing

    Open a ticket and get a case number, then confirm every phone call by email. With T-Mobile, the written record is what later moves the case forward.

  2. 2
    File regulatory complaints

    Complaints to Federal Communications Commission (FCC), State Public Utility Commission, FTC typically route to a team with authority to resolve, unlike frontline support.

  3. 3
    Send a demand letter by certified mail

    State the facts, the statute, the exact amount you want, and a 10–14 day deadline. Send it to T-Mobile's registered agent as well as customer service.

  4. 4
    File in small claims court

    If the deadline passes, file where you live. Bring your timeline, receipts, the demand letter, and the certified mail receipt.

T-Mobile-specific tips

An FCC informal complaint almost always routes to an executive relations agent with authority to issue credits. File it after your written demand letter.

Check T-Mobile's current BBB rating and complaint volume before you write — a pattern of similar complaints strengthens your own claim and is worth citing.
